Odds and Ends: Nabro Volcano and Texas Wildifres

September 15th, 2011 by Robert Simmon

 

Two more images that don’t quite fit on the main site: Nabro Volcano and the Riley Road Fire near Houston.

Nabro VolcanoNabro VolcanoThis long-dormant Eritrean volcano began erupting in June, but it’s so remote (at least for western media and scientists) that there’s been no news from the area for months. Unfortunately it’s often been cloudy, so we haven’t gotten any good satellite imagery, either. The best recent imagery is this false-color image (vegetation is red), which shows activity has ceased, although there may be a slight hint of gas emissions near the vent. We’re still trying for better imagery, and will post anything we get in our Volcanoes and Earthquakes section.
 

Riley Road FireCloser to NASA’s home is this photograph from last week of smoke from the Riley Road Fire, which burned 18,960 acres (7,670 hectares) near Houston, Texas (visible in the upper right corner). It was taken by an astronaut aboard the International Space Station, who could probably see his (the Expedition 28 crew is all male) house at the time.

Credit for the Nabro Volcano image goes to the the NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team, and credit for the Riley Road Fire to the Image Science and Analysis Laboratory, NASA-Johnson Space Center.
